Application

2-(Octadecyloxy)ethanol is widely used as a non-ionic surfactant in emulsion polymerization and colloidal systems. Its amphiphilic nature enables effective stabilization of nanoparticles and micelle formation in aqueous and organic phases. Researchers utilize it in surface coating formulations to enhance wetting and dispersion properties. Additionally, it serves as a key intermediate in the synthesis of specialty chemicals, including lubricants and plasticizers. Its biocompatibility also makes it suitable for exploratory biomedical applications.
